SPECIFICATION forming part of Letters Patent No. 411,6"/"7, datedSeptember 24, 1889.

Application led July 1l, 1889.

To all whom it may concern,.-

Be it known that I, EDWARD L. PHIPPs, a citizen of thc United States,residing at Milford, county of Oakland, State of Michigan,

have invented a certain new and useful Improvement in Car-Doors; and Ideclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to 1o make and use the saine, reference being had to theaccompanying drawings, which form a part of this specification.

In the drawings, Figure l is a side elevation of a car with one of myimprovd cardoors, showing by dotted lines the same partly open. Fig. 2is a side elevation of the same with parts broken away, and illustratingby dotted lines the operation ofthe mechanism.

My invention relates to that particular class of car-doors known asflush doors, which set into the side of the car flush with the outersurface of the car.

My invention consists of the peculiar combination of devices andappliances herein-- after specified, and more particularly pointed outin the claims.

A represents a car. B is its door. The door sets into the side of thecar flush with its face, and the door-jainbs at the top, bottoni, andsides are preferably beveled, as shown at b, so that the door shallwedge closely into its seat.

C is the rail or rod along which the cardoor traverses as it is beingopened. i 3 5 Brepresents hangers. They are attached to the door, and attheir outer ends are journaled into the lower ends of the uprightSuspenders D. These Suspenders loosely engage the rail or rod C at d,and a connecting-rod D serves to hold their upper ends in properrelation with each other.

E is a shaft extending across the doornear its top, and held by suitableclips c. At E is a crank, and at the ends of the shaft are crank-armsE2, the wristepins c2 of which engage with the Suspenders D by passingthrough slot-s d formed therein. The crank E is, by a pitman E3, engagedwith the crankarm f of the opening-lever F.

5o G is a locking-bolt, likewise engaged with the crank f. It engages asuitable socket Serial No. 317,117. (No model.)

g upon the sill of the door. The opening-le ver F maybe provided with aslot j", adapted to engage over a hasp f2, and the whole may be lockedby a padlock or any other usual appliance.

The operation of -the device is as follows: To open the door, the leverF is released and is lifted. This serves to draw the bolt G from itssocket, releasing the bottom of the door. 6c The motion of the lever,also, by lifting on the pitman'Eg, raises the crank E. This throws backthe crank-arms E2, and since they are resisted by the Suspenders D theresult is to carry the top of the door outwardly from the car. Thismovement of the door, by reason of the engagement of its hangers B withthe lower ends of the Suspenders, serves to swing the suspenders out atthe saine time, thus serving to throw the door still farther out- 7oward from its seat. Having raised the opening-lever F to its uppermostposition, the crank f will have passed slightly beyond the line ofresistance exerted upon it through the pitman E3, leaving the lever in aposition 7 5 of stable equilibrium, The door having been thus lifted outfrom its seat beyond the face of the car, it is slid open along the railor rod O.

.A stop C may serve to limit the movement in opening, and may also stopthe door in 8o closing at the proper point opposite its seat. To closethe door, it is slid to its place opposite the opening and the lever Fis turned down. As it is thus turned it forces the locking-bolt G intoits socket. It also pulls down the crank E. This throws forward thecrank-arms E2, which, being resisted by the suspenders D, serve to crowdthe door snugly into its seat. The lever F may now be suitably locked.9o

It will be observed that the shaft E is located between the hangers B Band rail C. This arrangement gives to it, in connection with theSuspenders D, the peculiar compound leverage mechanism shown, whereby asmall 9 5 rotation of the shaft serves to lift the door outward througha distance greater than the throw of the cranks E2.

I do not limit myself to the lever Fas a means for actuating the pitinanand so rotatloo ing the crank E', for this actuating mechanism may beconsiderably varied without departing from my invention; and I wouldhavemy claims understood to comprehend as equivalents any suitable mechanismfor aetuating the said pitlnan. The salne is true also of the means foractuating the lockingbolt G. v

What I claim isf l. The combination, with a ear-door and traversing railor rod, of Suspenders depending from said rod and engaged with hangersupon the door, a shaft provided with cranks E E2, turned in oppositedirections, the latter engaging through slots in the Suspenders,

a pitman E3, and crank-lever F, substantially as and for the purposesdescribed.

2. The combination, with a car-door and its traversing rod, of hangersupon the door engaged with Suspenders depending from said rod, a shaftprovided with cranksE E2, lo-

cated between the hangers and the rail, and in connection therewith apitman and cranklever -for actuating said shaft, substantially asdescribed.

The combination, with a ear-door and its rail, of hangers upon the doorand suspenders depending from the rail, withwhich the hangers areengaged, a shaft provided with cranks E E2, the latter engaged with thesuspenders by a slotted engagement, a pitman E3, crank-lever F, andlocking-bolt G, substantially as and for the purposes described.

In testimony whereof I sign this specification in the presence of twowitnesses.
